Threading
1. Definition- What is a thread?:
A thread is a variation on the idea of using an inclined plane to move an object. A thread can be used to convert torque into linear force.
Shown here is an image of a nut with internal threads and threaded rod with external threads.
Threads come in many types and forums some common types include - -American National and Unified Screw Thread (UN and UNF) -American Nation Standard Metric Scree Threads M Profile -Acme Screw Threads -Buttress Threads -Tapered pipe Thread
Each of these threads serves a different purpose and is optimized for a specific task.
2. Thread Making: Threads can be put onto a surface in a variety of ways. Some of these methods involve the removal of material while others relay of the reshaping of material. Some common methods include -Cutting using a tap or die -Cutting using a single point tool such as on a lathe or CNC mill -Tread grinding can be used to generate threads with very high tolerances -Thread rolling creates a thread by plastically deforming the material into the shape of a thread -Thread casting can be used to generated threads that do not require high tolerances.
